Simpson 8-3/4" Beam Column Cap CCO9 from Simpson is a heavy-duty column cap engineered to create strong, reliable column-to-beam connections on steel columns and posts. The legless design allows for direct field-welded attachment to steel columns, eliminating the need for pre-fabricated leg configurations and giving structural professionals greater flexibility on the job site. The extended seat of the cap reaches beyond each side of the column to provide additional bearing surface area, helping to distribute beam loads evenly and reinforce the overall connection point for long-term structural integrity.

Key Features

• Uplift load capacity increased for earthquake or wind loading - provides a more resilient connection in high-stress environments where lateral and uplift forces are a concern.
• Bolt spacing meets NDS code requirements - ensures the connection performs to recognized industry standards, simplifying the inspection and approval process.
• Diamond holes for temporary fastening - allow installers to hold the cap securely in position during alignment before final bolting or welding, improving accuracy and safety.
• Sized for 8-3/4 in. beam width - provides a properly fitted connection without modification, reducing installation time and guesswork on compatible framing members.
• 8 in. cap height - delivers adequate coverage along the beam depth for a secure, well-supported connection.
• Made from 3-gauge uncoated steel - the heavy 3-gauge thickness provides substantial load-bearing strength suited to demanding structural column-to-beam applications.

Why This Product

• Field-weld flexibility for steel column applications - the legless construction means this beam cap can be field-welded directly to steel columns or pipe columns, making it a practical choice for structural steel projects where pre-legged connectors are not suitable.
• Built for seismic and wind-load demands - with uplift loads specifically increased to address earthquake and wind loading scenarios, this column cap is a dependable choice for structures in regions subject to heightened lateral forces.
• Heavy-gauge construction for high-load connections - fabricated from 3-gauge uncoated steel, this beam cap is built to handle the rigorous demands of heavy timber and engineered lumber beam connections where connector strength is critical.
• Code-compliant fastener design right out of the box - bolt spacing is already designed to meet NDS code requirements, helping contractors and engineers move through the permitting and inspection process with confidence.

Frequently Asked Questions

What beam width is the Simpson CCO9 designed to fit?

The CCO9 is specifically designed for use with an 8-3/4 in. beam width, providing a secure and properly sized fit for that member size.

What fasteners are required to install the CCO9?

Installation requires four (4) 3/4 in. diameter machine bolts. Bolt spacing is designed to meet NDS code requirements for optimal performance.

Why does the CCO9 have a legless design?

The legless design of the CCO9 enables field-welded attachment directly to steel columns and posts, offering greater flexibility for on-site installation and connection to pipe or other column types.

Is the CCO9 suitable for use in seismic or high-wind regions?

Yes. The CCO9 features increased uplift load capacity, making it well-suited for applications where earthquake or wind loading must be accounted for in the structural connection design.
